Ensure that bio_endio() is called if io->error == DM_ENDIO_REQUEUE and

not really familiar with the dm code.

I did reinstate bio-based multipath recently. But I just want to make
sure: you realize that dec_pending() is only ever used by bio-based DM
right? (dm-mq and .request_fn multipath are request-based)
Hello Mike,
Yes, I am aware that this code is not triggered by my tests. This is
something I noticed while reading the dm source code and something I
wanted to report.
Bart.
